Turner depicts the backbreaking work of laborers shoveling coal from small boats onto a cargo ship in this nocturnal scene set in northeast England. The splendor of the full moon serves as a spotlight enabling round-the-clock labor. The glow of the furnace at right competes with the moon’s cool brilliance in a scene of almost surreal beauty. In the print, some of the indistinct qualities in Turner’s watercolor take on more defined form.
